A concise, expert guide to carb counts, taste, and keto compatibility for almond, coconut, macadamia, dairy, oat, and other milks.

For most keto eaters, a milk earns the "keto‑friendly" label when it delivers very low net carbs (≈0–3 g per 240 ml / 1 cup), no added sugars, and ideally contributes useful fat or protein. Because daily carb targets are tight, even a splash can matter—so labels and serving sizes matter more than marketing claims.
Dairy milk's natural sugar, lactose, lands at ~12 g net carbs per cup—enough to crowd your daily carb budget. Fat percentage (skim vs. whole) changes calories, not lactose grams, so even whole milk remains high‑carb. Most keto plans therefore swap toward unsweetened nut or seed milks, or use heavy cream in small amounts.
Carb Content: Skim, 2%, and whole all hover around ~12 g net carbs per cup. The lactose doesn't drop with higher fat.
Lactose & Insulin: Can nudge blood glucose—especially in larger servings. Use heavy cream in small amounts instead.
Carbs: Similar to cow's milk (~10–12 g per cup). Different casein structure may be easier to digest.
Taste: Distinct, slightly tangy flavor. The carbs remain the limiting factor.
Fat Content: Higher in fat and protein—rich and creamy.
Carbs: Still ~11–13 g per cup. Higher fat doesn't offset the lactose load.
Unsweetened: ~1–2 g net carbs per cup—very keto‑friendly.
Brands: Three Trees, MALK, Elmhurst (unsweetened). Avoid maltodextrin, rice syrup, tapioca starch.
Canned full‑fat: ~2–4 g net carbs per ½ cup. Thick, rich, ideal for cooking.
Carton: ~1 g net per cup. More diluted, great for everyday use. High in MCTs.
Low‑Carb: Usually ~1 g net carbs per cup. A premium pick.
Taste: Naturally creamy and neutral‑sweet, great for coffee and desserts.
Unsweetened: ~1–3 g net carbs per cup (sweetened varieties much higher).
Note: Contains isoflavones (phytoestrogens). Always select unsweetened.
High Carbs: Enzymes break oat starches into sugars, pushing carbs to ~14 g+ per cup.
Verdict: Not keto—even "original" varieties with no added sugar.
Cashew: ~1–2 g net per cup; silky texture.
Hemp: ~0–1 g net per cup; light, earthy; omega‑3 ALA.
Flax: ~0–1 g net per cup; very low carb.

|---|---|---|---|---|
| Almond (unsweetened) | ~1 g / cup | Low | 🥓🥓🥓🥓 | Best everyday option |

| Hemp (unsweetened) | ~0–1 g / cup | Low | 🥓🥓🥓🥓 | Earthy; omega‑3 |
| Flax (unsweetened) | ~0–1 g / cup | Low | 🥓🥓🥓🥓 | Very low carb |
*Values refer to 240 ml (1 cup) unless noted. Canned coconut shown per 120 ml (½ cup). Brands vary—always check labels.
Blend 1 cup almonds (soaked, drained) + 4 cups water + pinch of salt. Strain through a nut bag. Store 3–4 days.
Optional: Add vanilla and keto sweetener.
Blend ¾ cup macadamias + 3–4 cups water until silky. Strain for thinner texture or leave unstrained for extra creaminess.
Whisk ¼ cup canned coconut milk + hot espresso.
Optional: Add 1 tsp MCT oil for extra fat boost.
Sweeten with erythritol, monk fruit, or stevia and a splash of vanilla extract—no added carbs.
For strict keto, keep full servings of dairy milk and oat milk off the menu. Choose unsweetened nut/seed milks, check labels, and let small, strategic portions do the heavy lifting.
